在 mac os catalina 上调用 `run` 后 gdb 挂起

Question

系统：

mac osx catalina (10.15.5)
gfortran 9.3.0 (from homebrew)
gdb 9.2 (from homebrew)

经历并遵循以下说明：https : //sourceware.org/gdb/wiki/PermissionsDarwin

试图调试这个程序只是为了学习：

! test.f90
program main
  integer :: val
  val = 1
  print *, val
  val = 2
  print *, val
end program main

编译：

gfortran test.f90 -Og -g -o test

然后在终端

~/Coding/gdb
> ./test
           1
           2
~/Coding/gdb $
> gdb test

在这一点上什么也没有发生......它只是挂起并且无法用Ctrl-C杀死它，我必须去活动监视器杀死gdb。想知道我是否在设置中遗漏了什么，或者是否有人有任何其他想法为什么这可能是

因此，在使用 gdb 之前，您必须在主目录中创建一个“.gdbinit”文件。现在，每次 gdb 启动时，它都会执行该文件中的命令。“.gdbinit”是一个可以放在主目录中的文件，当 gdb 从命令行或从 Xcode 启动时，gdb 将解析该文件。

echo "set startup-with-shell off" >> ~/.gdbinit

运行此命令，当您使用 run 命令 aur r 时，gdb 不会挂起。
